Title: Electro-magnetic braking system for vehicles
IPC: B60T13/74
Filed: 1965-06-25
Abstract: 1,095,038. Electromagnets. BORG-WARNER CORPORATION. June 25, 1965 [July 2, 1964], No. 27105/65. Heading H1P. [Also in Divisions B7, F2 and H2] In a braking system for a tractor vehicle (see Division F2), a plurality of electromechanical braking units D is situated adjacent each of the vehicle wheels and a remotely disposed control unit B (not shown) is provided with a pedal for controlling each of the brake units. Each electromechanically-operated braking device D consists of a multi-plate brake which is adapted to be energized electromagnetically when the coil 58 is supplied with current, a self-servo effect being achieved by the provision of ball and ramp mechanisms G between the stationary end plate 33 of the brake housing and a movable ramp plate 42. The movable ramp plate 42 is adapted to be urged against a floating friction facing 49 which is disposed between the armature plate 24 and the movable ram plate 42. The floating friction facing imparts axial thrust from the ramp plate 42 to the armature 24 for the purposes of brake engagement. The electromagnet controlling the brake consists of a coil member 53 defined by a pair of annular rings 54 and 55 formed of ferromagnetic material. Each of the rings 54 and 55 being of L-shaped cross-section and assembled together with one leg of the L overlapping another leg of the L of an opposite ring so as to provide a generally U-shaped configuration to the coral member cross-section. The exposed annular terminal portions 56 and 57 of each of the rings are radially spaced apart to form magnetic polepieces. In order to increase the reluctance of the magnetic clutch path through the coil member 53 and thereby more quickly destroy the residual magnetism upon the energization of the coil member, an insulating shim plate 75 is disposed between the annular rings 54 and 55. Strap springs 78 are riveted to the radial surface of the coil member 53 so as to maintain a constant urging of the coil member into contact with the armature 24. To prevent deterioration of the annular polepieces during operation of the brake the annular ring members are case-hardened along all the exposed surfaces. This is followed by a cutting operation in which the case-hardened metal is removed from the friction faces 56 and 57 of the coil member.
